    23 juillet 2017, par user3743908

    I’m trying to convert a YUV422 image (YUV422_8_UYVY, unsigned ,unpacked, 16bpp) in to jpeg using ffmpeg’s ,this is Code which I am following

    Image size : 2448x2050
    Original YUV Image : not able to upload as the format is YUV

    (Original Image Decodec by ffmpeg command prompt)
    Image :This is original Image

    Image size : 2448x2050
    reconstruct Image :Reconstruct Image through above Code

    so the reconstruct image is not as the original image

    my format is UYVY whereas supported format is AV_PIX_FMT_YUVJ420P

    so what should be the correct format for UYVY input image...?

    pCodecCtx->pix_fmt=AV_PIX_FMT_ ?????

    if i use pCodecCtx->pix_fmt=AV_PIX_FMT_UYVY422 ;
    i got an arrer saying

    [mjpeg @ 00c0b2a0] specified pixel format uyvy422 is invalid or not supported

  • How to get decoded audio samples in libav

    22 mai 2020, par Desp4

    I'm trying to decode a non-planar wav audio file with libav, but the output file seems corrupted and a bit longer than the original. Am I handling frames wrong when writing them to a file like this ?

    



    


    fwrite(frame->extended_data[0], 1, frame->linesize[0], outFile);

    


    



    When opening the file in audacity it looks like this. Where two channels on top are from the original and the ones underneath are from a decoded file.
